Garmin GPSMAP 551s accessories Questions and Answers

Question: Looking at purchasing power cable for Garmin 551s and cover. Do I need a GPS antena as well. I thought this model had a GPS receiver in it. Thanks. Do you have these in stock

Answer: We have both the power cable and cover in stock. You are right to say that the Garmin GPSMAP 551s has a built-in GPS antenna. The remote GPS antenna is only needed if you would like to mount the Garmin GPSMAP 551s below deck and where it cannot achieve a GPS satellite fix.
